Atomic Energy in Medicine
ical environment on human activity and behavior, as well as the physical and climatic milieu. Unfortunately, the book is slanted. Since the author worked with Carrel, the writing is colored by the dualistic approach to the nature of man. While admitting that man is a physical chemical machine, his activity is governed in part not only by the physical laws of the universe but, also, by spiritual...
متن کاملSafety criteria in atomic energy.
The Problem The previous conference of this society dealt with the concept of tolerance levels in industrial activities. Today's conference has shown the importance of this concept in a new industry-that of atomic energy. The industry has an unfortunate history arising from its war-like introduction at Nagasaki and Hiroshima, and this has led to a considerable amount of confused thinking. Whene...
متن کاملRenewable energy deployment to combat energy crisis in Pakistan
The huge deficiency of electricity due to heavy reliance on imported fuels has become a significant impediment to socio-economic development in Pakistan. This scenario creates an increase in local fuel prices and limits potentials in the establishment of new industrial zones. The current gap between the demand and production of electricity in Pakistan is approximately 5000–8000 MW with a consta...
متن کاملEnergy dissipation in atomic force microscopy and atomic loss processes.
Atomic scale dissipation is of great interest in nanomechanics and atomic manipulation. We present dissipation measurements with a linearized, ultra-small amplitude atomic force microscope which is capable of measuring dissipation at chosen, fixed separations. We show that the dynamic dissipation in the noncontact regime is of the order of a few 10-100 meV per cycle. This dissipation is likely ...
